Plot
The ninja and Nya return to New Ninjago City, where they find a mob of angry civilians and Cyrus Borg, who is no longer influenced by the Overlord. The ninja agree to go underground to search for the Serpentine, believing that they stole the hard drive containing the Overlord, while P.I.X.A.L. stays behind to assist Cyrus. Meanwhile, the Stranger discusses his plans with the Digital Overlord to obtain a power source for the Nindroids, while Lloyd and Sensei Garmadon make their way through Hiroshi's Labyrinth to stay hidden.

The ninja and Nya search underground for the Serpentine, eventually running into Skales outside of the Serpentine village. Skales brings them inside and tells them how they have decided to adapt to a new life and become more "civilized," choosing not to become involved with any of the Overlord's plans, or involved with the world above as a whole. Acidicus then tells the group about the "Curse of the Golden Master," a legend telling of a being whose power will equal that of the First Spinjitzu Master. The Serpentine attempted to warn people of this but were treated as the enemy, to which they fled underground. In the meantime, Cyrus Borg meets with P.I.X.A.L. in his office, with P.I.X.A.L. telling Cyrus of her connection with Zane. Cyrus tells her that she doesn't belong to anyone, not even him and that she is fully independent.

Dareth also acts as the substitute teacher for Sensei Wu's students, as they go to the city's aquarium. There, while viewing the Electro-Cobrai exhibit, the Stranger arrives and shatters the tank. He obtains the Electro-Cobrai while Dareth fends off a shark, saving the students.

Underground, the ninja contemplates the situation until an army of Nindroids raids the tomb. The Serpentine scatter with the ninja defending them and defeating the Nindroids by finding out that the Electro-Cobrais are their power source. Skales tells them at the Curse of the Golden Master is upon them, and says that they would not be able to assist the ninja because they're choosing to stay out of the conflict. Skales then tells them the one Serpentine fond of using Electro-Cobrai. The ninja then return to the surface.

As Lloyd and Sensei Garmadon continue their journey, they're attacked by the corrupted Sensei Wu and various Nindroids. Garmadon battles Wu, while Lloyd uses his Golden Power to create a motorcycle to escape. He is pursued by various Nindroids using flight gear, although he manages to evade them all before coming to a stop next to a cliff. There, the Nindroid MechDragon rises up before him, possessed by the Overlord. Wu is holding Garmadon hostage on its back. Lloyd prepares to battle the Mechdragon, but the Stranger unleashes a snake that constricts Lloyd, draining him of his powers.

The Stranger then reveals himself to be Pythor P. Chumsworth, having survived his ordeal with the Great Devourer, although his skin was bleached white in the process while Wu made it out unharmed. Pythor brings Lloyd aboard the Mechdragon, after which Garmadon is pushed off the side and into the water. As the Mechdragon flies off with Lloyd, Garmadon emerges from the water, telling his son to be strong, and that he would find him.
